I had this with one client in particular.  Did a full backup and the 
problem went away for a while, then recurred.

Eventually I decided to try to track it down and contacted the machine 
owner for a time to get together and find more information about the 
problem.  A few days later I received a humbled call from the owner ... 
we was short on disk space and was trying to clean up files he didn't 
need.  Since he didn't know these needed to exist, he periodically 
erased them, leading to these messages!

He stopped erasing them and the problem disappeared at the next full 
backup.  In situations like this, I wish NetBackup would just revert to 
a FULL BACKUP, rather than backing up everything in an incremental.  (In 
the case related above, we were doing monthly full backups with all 
incrementals in between (to save him $$ ... we charge back for amount of 
data in our backup server) ... backing up everything every night gave 
him quite a surprise at the next billing!).

An alternative is to omit TIR from the backups, but this reduces the 
value of the backups and may not be appropriate in your case.

I've also had this happen occasionally with some WinXP laptops, but 
haven't figured out why, though it's particularly possible with those 
that an incremental was terminated due to the laptop being 
unceremonially disconnected from the network.

Hope this helps, wayne
